This weekend the glowing, pregnant Duchess Kate bundled up and headed to the Swiss Alps with Prince William to attend the wedding of their friends, Olympian Laura Bechtolsheimer and professional polo player Mark Tomlinson.

Us Weekly notes that Kate arrived in the mountains with Prince Harry; Prince William had arrived previously to prepare for his duties as an usher. The duchess covered her growing bump with a cream coat with a warm brown fur trim and a matching Lock & Co. pillbox hat, with a Max Mara dress underneath. She also appears to be joining in on the celeb tradition of wearing heels throughout her pregnancy. The duchess walked "gingerly up the steps to the church," an onlooker at the ski resort in Arosa told People magazine. "She was being very careful in her heels."

The Daily Mail has pictures of the duchess resting her hand on her growing belly and smiling widely while throwing confetti upon the bride and groom as they exited the church. The couples have long been friends: Prince William regularly plays polo with Tomlinson, who went to college with Kate, and Bechtolsheimer and (royal cousin) Zara Phillips both placed on the London 2012 Olympics team.

No skiing for Kate on this trip though. While Prince William and Prince Harry took a trip down the slopes, PopSugar has shots of the duchess with a sled in her hands instead.
